[postgis-users] Problem with ST_WITHIN

[Luigi Castro Cardeles]

Hi list,

If i run that query,

select ST_Within
    (
        geomfromtext('POINT(10 18)',4326),
        geomfromtext('MULTIPOLYGON (((10 18,30 18,30 12,10 12,10
18)))',4326)
    )

or

select ST_Within
    (
        geomfromtext('MULTIPOLYGON (((10 18,30 18,30 12,10 12,10
18)))',4326),
        geomfromtext('POINT(10 18)',4326)
    )

this query return false.

If i try

select ST_Within
    (
        geomfromtext('POINT(10 18)',4326),
        geomfromtext('POINT(10 18)',4326)
    )

this query return true.

Is this right?

I think that the first query should return true. Am i wrong?

best regards,
